- Serializer - a translator between XML-based data and serialized data; used as an
entry point for serializator tool;
- Printer - an entry point for printer tool;
- - FlatBuffers - a library used for management of serialized data.
+ - FlatBuffers - a library used for management of serialized data (deprecated).
- Classes-use-only-serialized - a diagram of classes; this is improved Classes;
the differences are:
of Classes-use-only-serialized; the differences are:
- There is no StorageBackendXML;
- Serializer uses XmlParser to create FlatBuffers directly (in case of unavailable
- serialized policy file);
+ serialized policy file) (deprecated);
- we are not sure if this will improve initialization time, as all the objects have to be
fully created before serialization anyway.
Google's FlatBuffers (https://google.github.io/flatbuffers/) were selected to implement
serialization. In order to do that, the code was heavily refactored.
+In 2020, we replaced FlatBuffers with locally implemented, direct serialization.
